Mounting structure of automobile sound-absorbing cotton and automobile

Abstract

The invention relates to an automobile sound-absorbing cotton mounting structure and a vehicle, the automobile sound-absorbing cotton mounting structure comprises a frame, the frame is provided with a filling cavity corresponding to the position of an interior trimming panel, and the filling cavity is filled with sound-absorbing cotton; the foldable support is arranged on the outer side of the sound absorption cotton in a press fit mode, the foldable support extends from one side of the filling cavity to the other opposite side of the filling cavity, and the two opposite ends of the foldable support are installed on the frame. According to the mounting structure of the automobile sound-absorbing cotton and the automobile, the sound-absorbing cotton can be directly plugged into the filling cavity of the automobile frame and can be pressed through the foldable support on the outer side, holes do not need to be formed in the sound-absorbing cotton, and the sound-absorbing cotton and the automobile frame do not need to be bonded and fixed, so that the defects of bonding and laser welding are overcome, and the production efficiency is improved. The cost of using the adhesive tape is greatly reduced, the indoor VOC and environmental protection indexes are improved, holes do not need to be formed in the sound-absorbing cotton, the laying area of the sound-absorbing cotton is maximized, and the indoor sound insulation performance is greatly improved.

Description

technical field [0001] The invention relates to the technical field of commercial vehicle NVH, in particular to an installation structure of sound-absorbing cotton for automobiles and a vehicle. Background technique [0002] At present, when commercial vehicles / cars are improving NVH (Noise, Vibration, Harshness) noise, sound-absorbing cotton is often filled between the metal body and interior panels to absorb and isolate noise from the outside world. [0003] In related technologies, there are generally two ways to fix the sound-absorbing cotton to the vehicle body, one of which is to arrange tape on the back of the sound-absorbing cotton to stick the sound-absorbing cotton to the surface of the metal body; the other is to weld the sound-absorbing cotton inside by laser welding The surface of the decorative panel, so that the sound-absorbing cotton and the interior panel form a composite. [0004] However, each fixed point of the sound-absorbing cotton in the bonding metho...
